Page 1 of 6 <br />SOP NUMBER 0.0 Well Development <br />1.0 PURPOSE AND SCOPE <br />This Standard Operating Procedure (SOP) provides teclmical guidance and methods that will <br />be used and procedures to be followed for developing groundwater monitoring wells. This <br />SOP gives descriptions of equipment, field development procedures, field data collection, <br />and personnel responsibilities. <br />The purpose of well development is to restore the hydraulic conductivity of the aquifer material <br />surrounding the well to near pre -well installation conditions. This is accomplished by removing <br />well drilling fluids, solids, or other particulates that may have been introduced or deposited on <br />the borehole wall during drilling and well constriction activities. Properly developed <br />monitoring wells allow for the collection of representative groundwater samples. <br />2.0 RESPONSIBILITIES AND QUALIFICATIONS <br />The Project Manager or Field Manager have the overall responsibility for implementing this <br />SOP. They will be responsible for assigning appropriate environmental staff to implement <br />this SOP and for ensuring that the procedures are followed. <br />All personnel performing these procedures are required to have the appropriate health and <br />safety training. In addition, all personnel are required to have a complete understanding of <br />the procedures described within this SOP, and receive specific training regarding these <br />procedures, if necessary. <br />All envi oninental staff and assay laboratory staff are responsible for reporting deviations <br />from this SOP to the Project Manager or Field Manager. <br />3.0 RELATED STANDARD OPERATING PROCEDURES <br />The procedures set forth in this SOP are intended for use with the following SOPs: <br />SOP No. ** Groundwater Sampling <br />SOP No. ** Monitoring Well Water -Level Measurement <br />SOP No. ** Decontamination of Sampling Equipment <br />SOP No. ** Field Parameter Measurements (including Instrument Calibration) <br />SOP No. ** Monitoring Well Installation <br />4.0 EQUIPMENT LIST <br />The following items will be required to develop groundwater monitoring wells: <br />• Well completion logs <br />• Well development records (see Attachment A) <br />o Well keys <br />• Stainless steel, adjustable rate, submersible pump, controller, and power source (generator <br />or battery) <br />0 -1 <br />
